SPECIFICATION forming' part Of Letters Patent NO'606,658," dated July 5, 1898.

Application tiled July 26,1897. Serial No. 646,027. (No model.)

. GIBSON, a subject of the Queen of Great Britain, residing at The Rectory, Chulmleigh, North Devon, England, have invented certain new and useful Improvements in Machines for Punching Telegraphic Paper, of

which the following is a specification.

According to this invention all the punches used for each letteror character are automatically put into operation by depressing.

the corresponding key on a keyboard. For this purpose the act of depressing the key makes a number of contacts, closing a number of circuits through electromagnets,where bythe valves of pneumatic cylinders operating the punches are shifted.

Figure l is an elevation of one of the finger-keys, and Fig. 2 an elevation of one of the circuit-@losers actuated by them. Fig. 3 is a plan, and Fig. 4L a sectional end elevation, of the punching-machine. Fig. 5 is a sectional elevation of the supply and exhaust valve. Fig. 6 shows a piece of the punched paper produced. Fig. 7 is an elevation showing a detail of the feed mechanism. Fig. 8 shows a modification.

o, Fig. 1, is a linger-key carried by a lever a', pivoted at a2. There is one such key to each letter or character employed.

as are projections on the under side of the levera, arranged above the transverse bars b to Z914. Each of these bars is mounted as a parallel ruler by links B from fixed rods B, as shown in Fig. 2, and its end bearsagainst a spring-contact maker.' B2, so that when a bar is depressed a circuit is closed. Six of these circuits actuate, as hereinafter 'described, punches perforating a strip of paper with holes to correspond to dots in the Morse code and also central holes to feed the paper, six perforate holes to correspond with dashes and also central holes, one perforates a central hole only, and one operates the air supply and exhaust valve. The right-hand end of Fig. 6 shows the result of operating all the 'punches simultaneously, the holes being marked h2 to Z714 tocorrespond with the bars closing the circuits producing them. It must be understood, however,that the two punches on both sides of the center of the paper are never in practice depressed simultaneously,

as this would be equivalent to sending at the same -moment a dot-and-dash signal. The actual results produced are such as areshown in the remainder of Fig. 6. The paper shown is that commonly used for submarine teleg- .raphy It will be obvious, however, that the machine may be modified to punch paper for a Wheatstone transmitter. Everylever a has projections CL3 above the bars h' and b2, that above the former being of such a size that this bar is not depressed till after the others. In addition to these two projections each lever has a projection or projections above one or more of the other bars corresponding to the dots and dashes making up the letter or sign marked'on the key.

. c2 to 014, Figs. 3 and 4E, are magnetsthrough which circuits are closed by the bars Z9 to Z314, respectively. The armatures of the magnets c2 to c14 are carried by Hap-valves cZ,fFig. 4, in air-chests CZ', connected by pipes d2 to each other and to the air-supply valve, Fig. 5. In this figure, c is a pipe connected to a reservoir of compressed air, and c' e2 are valves on a common spindle, connected bya lever e3 to the armature of the magnet c. The valve e leads to the air-pipe e, and e2 to the outer air.

The chests CZ open into-cylinders f, having pistons f', piston-rods f2, and springs f3, tending to force the pistons outward'.v The various pistonerods]2 are pivoted to the lower ends of arms g2 to Q14. The upper endsof the arms g2 to g4 and Q6 to Q14 are fixed to sleeves h2 to h4 and h6 to Z114, working one inside the other on two shafts j j?, the arm g5 being fixed to the shaft j. The sleeves and the shaft j have fixed to them arms k2 to 7cm, resting on the heads of the punches Z2 to ZM, the last twelve being side punches and the lirst a central punch.

Each of the punches Z3 to Z14 has a collar L, Fig.4, on it bearing on one or other of six cross-pieces L, each -of which carries one of the remaining central punches Z15 to Z20, s0 that each time one of the punches Z3 to Z14 is depressed the corresponding central punch is depressed also.

Then one of the finger-keys a is put down, three or more of the bars b' toh1f1 are depressed by it, closing circuits through the magnet c2 and one or moreofthemagnets c3 to c11 and immediately afterward a circuit IOO through the magnet c. The effect is to open the corresponding flap-valves d and then open the air-supply valve e', so that air rushes into those cylinders whose valves have been opened, so depressing the punch Z2 and one or more of the other punches. Vheii the lingerkey is released, the circuits are broken, the valve c2 opens, the cylinders exhaust, and the Hap-valves close.

In order to feed the strip of paper forward after the holes correspondiii to each eharacter have been punched, the following arrangement is adopted: The central punches are prolonged upward, (see Fig. 4,) and above their heads are arms m2 and m15 to m2", which are omitted in Fig. 3, iixed to a shaft or sleeve n, (see Figs. S, i, and 7,) to wliiehis also fixed an arm n', connected by a link n?, lever n3, and link 'nfl to a lever n, carrying a pawl n gearing with the teeth of a ratchet-wheel n, fixed to the shaft ns, which also carries the pin-wheel 719, by which the paper is fed. The arm m2 iioi'inally rests upon the punch Z2, while the other arms are not normally in contact with their punches; but when the punch Z2 descends the shaft a is turned by the spring n10 until it is arrested by the arm m15 coming onto the punch 21"". Similarly if this punch descends the shaft again turns until ml comes onto Z1, and so on. When the punches are released,they are raised again by their springs turning the shaft n back again toits original position and propelling the ratchet-wheel 717. Thus the angular movement of the shaft n, and consequently the feed of the paper, depends upon the ii uinbei of holes made in the paper by the central punches-that is, upon the length of the character.

The air-cylinders and the electromagnet el may be omitted, the electromagnets c2 to c14 being made more powerful and having their armatures fixed tothe arms g2 to y, as shown in Fig. S. In all other respects the arrangement is the same as that above described.
